Iko Plane Bearing Noise Inspection And Maintenance

Iko Plane Bearing 

In order to judge whether the disassembled bearing can be reused, check after IKO bearing is Iko Plane Bearing cleaned. Carefully check the state of raceway surface, rolling surface and mating surface, the wear of cage,

the increase of plane bearing clearance and whether there is Iko Plane Bearing damage or abnormality related to the decline of dimensional accuracy. For non separable small ball bearings, support the inner ring horizontally with one hand and rotate the outer ring to confirm whether it is smooth.

Tapered roller bearings and other separable bearings can inspect the raceway surfaces of rolling Iko Plane Bearing elements and outer rings respectively.

Since large bearings cannot be rotated by hand, pay attention to the appearance of rolling elements, raceway surfaces, cages, edge retaining surfaces, etc. the higher the importance of bearings, the Iko Plane Bearing more careful the inspection is.

The judgment of whether the IKO bearing can be reused is determined by considering the damage degree, mechanical performance, importance, operating conditions and the period until the next maintenance. However, if there are the following defects, it can no longer be used. The bearings must be replaced with new ones.

Although the noise caused by manufacturing factors of plane bearing is essentially caused by Iko Plane Bearing manufacturing error,

it is still related to the selection of lubricant, the installation conditions of bearing and the accuracy state of shaft and bearing seat. This kind of noise can be divided into cage Iko Plane Bearing sound and vibration ripple sound, which are described as follows:

Iko Plane Bearing Noise Inspection And Maintenance

(1) Cage sound and its control method cage sound

refers to the periodic vibration and noise caused by the impact of violent vibration cage and rolling body, which is easy to appear when the pocket hole is loose and the friction is large. This kind of noise mainly occurs in ball bearings and IKO bearings, as well as stamping cages and solid cages.

It occurs when grease lubrication or oil lubrication is used, but it is more likely to occur when the lubrication is poor or the lubricant is dry, the radial clearance is large, the outer ring bears torque load, and the structure of the retainer is poor and the accuracy is not high, In severe cases, the cage web or rivet head will break suddenly.

The methods to control the noise and vibration of cage are as Iko Plane Bearing follows:; Use lubricants with good lubrication performance; Reduce the installation error of bearing;

The radial clearance of the compression bearing shall be Iko Plane Bearing properly preloaded axially, and the plane bearing with a cage with good accuracy and reasonable structure shall be selected, or the IKO bearing with a solid cage without wear shall be replaced.

(2) Vibration ripple sound and its control method vibration ripple sound is a noise directly related to the waviness of the rolling surface of plane bearing. It is a kind of pure tone noise. For a constant speed, its frequency remains unchanged, while for a changing speed, its frequency also changes.

Routine Inspection And Maintenance Of Iko Plastic Bearings

Influence Analysis Of Iko Non-Standard Bearing Lubrication Method On Performance

The oil seal package of IKO bearing can be removed immediately before delivery for routine inspection, and it can be immersed in washing Iko Plane Bearing gasoline or acid free kerosene containing 3% engine oil.

Turn its outer ring and carefully wash the junction of cage, rolling element and raceway. It is required to thoroughly clean the original oil traces left in any hidden parts. After the plastic bearing is cleaned, the attached cleaning oil shall be drenched dry and placed on the workbench lined with clean neutral lining paper to dry,

or dried slowly in the far-infrared oven. The bearing ring, cage or any rolling element shall not be rotated during the whole process from Iko Plane Bearing washing oil drying to air drying or drying.

The bearings that have been dried or dried shall be dripped with lubricating oil according to the regulations and delivered for inspection immediately. At this time, the outer surface of the plastic bearing is not protected by oil film. It is not allowed to directly touch the skin of hands during the whole inspection process.

The operator shall wear clean gloves or apply antirust agent on his hands, but the antirust agent on his hands must not be mixed with the rolling surface of IKO bearing, Iko Plane Bearing Otherwise, the measurement results will deviate.

IKO bearings shall be delivered for use or treated with anti rust stock immediately after inspection. The whole inspection process shall also be completed quickly to avoid corrosion caused by too long. Note that using pure gasoline without engine oil for cleaning will also cause corrosion.

Before inspection, the bearing must be placed on a metal plate in the Iko Plane Bearing inspection site together with the gauge block, standard parts and measuring instruments used for inspection, so as to homogenize the temperature and room temperature of these objects quickly.

Obviously, only by strictly doing the above preparations can we ensure the accuracy of the inspection results and prevent the plastic bearing from rusting in the whole inspection process.

1. Cleaning:

When removing the bearing for inspection, first make appearance records by photography and other methods. In addition, the amount of remaining lubricant shall be confirmed and the lubricant shall be sampled before cleaning IKO bearing.

a. The cleaning of bearings is divided into rough cleaning and fine cleaning. Plastic bearings can be placed with metal grid at the bottom of the container.

b. During rough cleaning, use a brush to remove grease or adhesion in the oil. At this time, if the IKO bearing is rotated in oil, pay attention to the damage to the rolling surface due to foreign matters.

c. During fine cleaning, the plastic bearing shall be slowly rotated in oil and shall be carried out carefully.

The commonly used cleaning agent is neutral water-free diesel oil or kerosene, and sometimes warm lye is used as needed. No matter what kind of cleaning agent you use, always filter it and keep it clean.

After cleaning, apply antirust oil or antirust grease on the bearing immediately.

2. Inspection and judgment:

In order to judge whether the removed IKO bearing can be reused, the plastic bearing should focus on checking its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring.

The inspection results can be judged by those who use inertial bearings or are proficient in bearings.

The judgment standard of plastic bearing varies according to the mechanical performance, importance and inspection cycle. IKO bearing shall not be reused and must be replaced in case of the following damage.

A. fracture and defect of bearing parts.

B. stripping of the rolling surface of the raceway surface.
